Guess the output:

   >>> def exec_code_object_and_return_x(codeobj, x):
   ...     exec codeobj
   ...     return x
   ...
   >>> co1 = compile("""x = x + 1""", '<string>', 'exec')
   >>> co2 = compile("""del x""", '<string>', 'exec')
   >>> exec_code_object_and_return_x(co1, 1)
   # What do you get here?

Decoding Base64-URL without padding

1) Add padding

Divide the length of the input string by 4, take the remainder. If it is 2, add two = characters at the end. If it is 3, add one = character at the end.

You now have Base64-URL with padding.

2) Translate to Base64
